DIY Privacy Display Question EDIT: Killed Laptop

[carl44463]

Sorry if this is posted in the wrong place to post idk. I am trying to recreate the monitor Luke makes in the video below. I am planning on doing this on an old latitude laptop. My question may be stupid, but do polarized sunglasses work instead of making your own glasses out of a sheet or the previous film?

EDIT: I killed the laptop's screen. :c

I think polarization only works if the lenses are arrange in the same way as the light being emitted.

You can try, but it would be best to also keep the display polarizer incase, that the sunshades don't work

As long as the screen is polarised correctingout should work. When I look at my screen through sunglasses it blacks it out completely when perfectly vertical and fades in when I tilt my head left and right.
